In relation to my previous post, it’s not like the NYPD didn’t used to shoot a lot of people.
There are two trends going on here. Police-involved shootings always reflect homicide numbers. (Cops are more likely to shoot a murder with a gun.) So there’s a spike in 1990 the then a big drop after that, which reflects crime in NYC. But even taking that into account, there’s a long-term downward trend. I have no idea what the long-terms trends in Oklahoma have been.
